"I'm actually doing these kinds of things, right now, with those "high-power LEDs" of yours."
I guarantee you are NOT working with anything CLOSE to the power range I'm working on. Even then - you aren't soldering a lead to the thermal pad of a 1W LED and getting it to operate at FULL DRIVE for more than a few seconds before it burns itself out. You've just totally screwed the thermal profile of the LED. There's a reason it has a huge 5x7mm pad and not a tiny-ass leg like your cheap-ass 5mm 'High power' LEDs.
Go mount a tiny leg to an MK-R and drive it full power, and try using that tiny leg for a heat transfer mechanism.
"That's assuming that a "storage capacitor" and a traditional capacitor are the same thing. I didn't."
You should, because a capacitor is storage/filtering and nothing else, period. Exactly like a battery, except it has a far, far higher rate of charge and discharge, and can undergo many, many, many magnitudes of order higher charge/discharge cycles versus a battery.
"Heck, there are already batteries that are more than just simple batteries. For example, ones with temperature sensors for charge control."
That's more of a safety requirement than a feature due to the particular characteristics of the underlying battery chemistry.
No, an ideal storage capacitor will simply store and release energy at maximum possible speed, and nothing more. Diodes and resistors act as flow control valves. Can you imagine the insane PITA it would be to find a proper capacitor with the right diode voltage drop and proper resistor built-in for the job you need?
This is why electronic components (excepting ICs) are individual pieces and not mashed together in the manner in which you describe.
Radioshack does indeed exist. Many stores just became combo RadioShack/Sprint stores. Sprint gets one half, RS gets the other. Stil got the big drawer full of components, with a rack of solder and irons right above it, as usual.
QFNs are even simpler than BGAs as you've got one MASSIVE central thermal pad to solder and a few pads around the edges to solder. Hot air soldering iron gets the job done in about 15 seconds.
Making the connections is indeed the issue. Some BGAs are so dense that you need a minimum of 4 layers to get the reliable separation required for clean signals down-trace.
Hell, I don't even use tweezers. Most SMT components are so lightweight that simply pressing on them with your finger so it stick to it then pressing them to the paste affixes them in place for oven work.
"As far as I know, if you are using these SMT components, you need a SMT assembly line and oven to build you design."
No, you don't. Not even close. You can do just fine with a 600/1200w hot air gun from harbor freight and some flux-core solder from radioshack. Or you can build a wire pen for finer lead work.
And not all surface-mount stuff requires hot air reflow techniques. I can hand-solder 2mm micro-capacitors using a soldering iron with a pencil-thickness tip.
All you need is a good printer with high-DPI for mask printing, and a proper technique that involves pre-tinning the BGA pads on the PCB, then setting your BGA part on the board and heating up the board to reflow the solder. The component will align itself without shorts due to surface tension from the solder.
I've done plenty of memory stick and GPU mounting/re-mounting work.
I work with traces in the single-digit micron range working on repairing LCD screens.
"It seems likely that the malicious Javascript was added by some SJW that works for imgur."
No, this was done by a notorious furfag on 8ch by the name of Bui. The fact that the originating SWF url comes from the/pokepaws/ board is pretty much the dead trigger, since Bui owns that board.
"If you're prototyping, why in hell not use "hole-mounted stuff"?"
Because the capacitors with the uF ratings I require are SUB MILLIMETER and SURFACE MOUNT *ONLY.*
Because the ceramic high-wattage resistors I use are SURFACE MOUNT ONLY.
Because the LEDs I use are SURFACE MOUNT ONLY.
Because you can't hole-mount a BGA package without adding in another component and thus forcing you to redo all your damned math to take into account the added resistance of a connection adapter.
Because most breadboard designs are garbage.
Because breadboards aren't made of metal like MCPCBs and are thus useless for my high-heat design work.

"VW also manufactures vehicles in the US, so if they were to go out of business in the US, that plant would have to close."
Good, maybe our workforce can be put to use making fucking domestic products instead of making foreign products for foreign companies that violate our laws.
Well, with "Paleo" in your name, I'm quite guaranteed you don't have a clue what you're talking about. As if you had a fucking clue what "Paleo" really means.

"Do you think Dell builds their own boards? They don't."
As a former HP and Dell engineer, uh, yes, they do.
They build the original design and then hand that off to a company for mass production.
Google does NOTHING OF THE SORT. They used pre-built designs that fit their particular form factor and desired specs.

"SMDs are not a problem- solder leads to the SMDs, and then proceed as usual."
Yea, you try that with thermally-sensitive things like high-power LEDs and see how long that prototype lasts.
Hell, I don't even use tweezers. Most SMT components are so lightweight that simply pressing on them with your finger so it stick to it then pressing them to the paste affixes them in place for oven work.

Not in this day and age of surface-mount components, they are not.
